## all stages in the pipeline
stages:
  - build
  - test
  - coverage
  - checkstyle

variables:
  ## 'clean' is necessary for JaCoCo aggregate report
  ## --batch-mode will avoid asking input in the terminal
  MAVEN_CFG: "clean --batch-mode"

## this stage will compile the source code in the project
## stage fails when the project failed to compile
build:
  stage: build
  script:
    - mvn $MAVEN_CFG compile

## this stage will run all tests in the project
## stage fails when one or more tests are failing
test:
  stage: test
  ## make the code coverage reports created in this stage available to further stages
  artifacts:

    - mvn $MAVEN_CFG test jacoco:report jacoco:report-aggregate

## this stage will output the code coverage in the terminal
